Hey, I just upgraded my bios and when I rebooted I got a message that said Checksum CMOS and another option that said Reset to Default Values. So I clicked Reset to Default Values and I didn't get the message again. Everything worked great but my games still froze. So I flashed the bios again and same message. So I went into the bios and exited out and it booted into windows right after I exited out, and my games didn't freeze. So everytime I boot I have to go into the bios and exit out.
